ABE L. WEBSTER, OF NEW YORK, N. Y;

Letters Patent No. 106,008, dated -Augulst2, 1870.

The Schedule referred to in these Letters Patent and making part of theme.

To all whom it may concern:

Be it knownthat I, ABEL L. Wnn's'rsn, of thc'city of New York, in the State of New York, have invented a certain new and useful Improvement in Pumping Fluids from Air-tight Chambers or Vessels; and I do hereby declare that the following is a full, clear, and exact description of the construction and operation or" the same, refereiice being had to the ac-' companying drawing and the letters and marks there'- on, which said drawing forms part of this specification, and shows the means for carrying out my invention.

Figure 1-+ F is a tube, leading from the opening above, which is closed by cap or lock marked K, to the bottom of zit-tank or other vessel from which fluids'are forced.

' G is an air-passage, leading from under side, from 7 vent-closing .cap L to the vacuum of a vessel from which fluids are forced.

H is the air-duct or passage by which the air isforced into the air-passage G.

L is a lock-nut or screw-cap, for closing air-passage G.

M is..a socket-screw, by which the air-passage H is connected with the air -passage Gt r N is ascrew-cap, for closing air-passage H.

Figure w A is a tank or closed vessel, fron'i'which fluids are forced.

B is the passage for the liquids leading from the tank A.

G is an air-tube, fromwhich the air is forced into the air-passage D.

Dis an air-passage,by which the air is passed into the air-tank A. a E is an air-vent, leading into the airspassage D.

Figure 3 is a sectional viewof Figure 7, showing the manner of .vent-ing. I

Figures 4 and 5 are used for the same purposes as Figure 6 is'a sheet-metal nozzle" or in-ificwthrough which fluids are poured into and out of closed vessels, such as cans, .860.

.Now, from the general character and construction of the means here shown, it will readily be perceived that the elevation of the fluid or other-material to be moved is atfected'by the pressure of. atmospheric air, which may be applied directly to the surface of the fluid by the continuous action of an air-pump, or be applied by a tube, leading from a chamber of aircompressed to any desired degree, and controlled by keys or faucets, to regulate the degree of pressure to be exerted on the surface of the fluid. Now, what I claim as my invention, is- The fluid-passage F and air-passage G, arranged concentric to each other, in combination with the supply-pipe Q and cap L for closing the air-vent E, substantially as" set forthy This specification signed this 6th day of June,
